About remapping

The John Deere 6820 is an agricultural tractor of the 6020 series and accounts for 7 files in our catalogue, entirely the 6.8 litre engine block. It is a high-power machine for demanding farm work.

Stage 1 accounts for all 7 files — a completely clean profile with no maintenance work at all. The ECUs are John Deere's own references: L14 and LXX. In agriculture we always work to conservative criteria.

Frequently asked questions

How does this differ from the 6620?

They belong to the same 6020 series and share the 6.8 litre block, differing in output rating. Our experience with one applies largely to the other.

What do you aim for when remapping a tractor?

Sustained pulling capacity and contained fuel consumption per hour of work, which is what matters on a farm.

Does it affect the machine's warranty?

It may affect the manufacturer's cover. We keep the original file so the work can be reversed if needed.

Data comes from our project history. Exact availability is confirmed when you request the file.
